In the general case where getByModSeq is called with a start == end,  
there is no need to do a query to the database, as the answer (an  
empty array) is already known (when these two are equal,  
history_modseq can never be both > AND <= to this value). Since this  
will be the case most of the time, it is much cheaper to check this  
before doing a database query.
